MGI Phenotype

PHENOTYPE: Mice homozygous for a null allele exhibit decreased insulin granule fusion in pancreatic islet cells during the first phase of cAMP-dependent insulin granule exocytosis. Mice homozygous for a knock-out allele exhibit impaired isoproterenol-induced SR calcium leak and arrhythmia. [provided by MGI curators]
